- The call
- The old deadbolt has grown lazy. You turn the thumb-turn and the bolt creeps out halfway, then needs a second push with the door pulled tight. Some mornings the key has to be jiggled before it will come back out.

The bolt on the front door is keyed on both sides. Getting out at night means finding the key in the dark, and with a toddler in the house you have decided the inside should turn by hand.
Deadbolt installation puts a solid bolt lock on a door that either has none or has one that is past its useful life. Unlike the spring latch in a knob or lever, a deadbolt is a straight bar of metal that only moves when the key or thumb-turn moves it, so a card slipped into the gap or a shove against the door does nothing. The locksmith bores the door if needed, fits the bolt and cylinder, cuts a proper pocket in the frame and secures a reinforced strike with screws long enough to reach the framing. You are left with a door that locks with a firm, full throw.

Deadbolt Installation · Hamilton

Scene 1
A bolt is only as good as what it throws into, so the jamb gets a hard look before anything is ordered. The locksmith checks whether the jamb is wood or steel, whether it is backed by solid framing at lock height or by a gap of shims and air, and whether earlier screws have torn out or been stripped. A jamb that flexes under a palm tells its own story. Where a strike has been fitted before, the old pocket is examined for depth and position, since a shallow or offset pocket is the usual reason an existing deadbolt feels stiff. This check decides between a plain strike, a reinforced strike with long screws, or a full-length jamb reinforcer.
Scene 2
A reinforced strike or strike box is centred over the pocket, squared to the edge of the jamb, and its outline is scored and chiselled to a depth that leaves the plate flush. Pilot holes are drilled, and the two holes nearest the door stop take 75 mm screws that pass through the jamb and the shim space into the stud behind, with shorter screws in the remaining holes. The long screws are driven by hand for the last turns so the heads seat without crushing the jamb. Where the jamb is thin or has been split by an earlier attempt, a full-length jamb reinforcer is fitted under the strike instead.
Scene 3
A deadbolt installation usually leaves the whole entry better than it found it. Hinge screws that were loose have been replaced with longer ones that bite into the framing, so the door hangs square. Weatherstrip that pinched the door has been trimmed and the latch below the new bolt has been checked against its own strike. The bore edges are clean, any shavings and steel filings have been vacuumed from the sill and the core, and the finish around the new hardware is unmarked. Open and close the door a few times over the next week and let the locksmith know if anything changes as the door settles.

Two measurements decide whether a deadbolt fits your door. Bore is the diameter of the big hole through the face, 54 mm on most current hardware. Backset is how far the centre of that hole sits from the door's edge, 60 mm or 70 mm on nearly all residential doors. A replacement must match both to use the existing holes, and a fresh installation is cut to match the knob below, so knowing them ahead puts the right hardware on the van.
A replacement into existing holes is generally the shorter visit, and boring a fresh door with a new strike takes longer, roughly an hour or two per door including the frame work and testing. Steel doors, keying alike, frame repairs after a forced entry and fitting a jamb reinforcer each add time. The locksmith can give a realistic estimate once the door and frame have been looked at.
Know which doors you want bolted, what they are made of, and whether each already has a deadbolt or only a knob. A photo of the door face and edge helps. Have any existing keys to hand, decide whether you want everything on one key, and mention glass near the lock, a storm door in the same opening, or a rental agreement. If you have already bought hardware, keep the box and template together.
